To all whom it may concern.-

Be it known that we, LAWSON TARWATER and CHARLES K. MOKNIGHT, citizensof the United States, residing at St. Joseph, in the county of Buchananand State of Missouri, have invented certain new and useful Improvementsin a Revoluble Reclining Railroad-Coach Chair; and wedo declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appert'ains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference'marked thereon, which form a part ofthis specification.

Our invention relates to a revoluble reclihing-chair especially adaptedto use in railroad-coaches, and we accomplish our object by themechanism illustrated in the accompanying drawings, in which Figure 1 isa front elevation of the pedestal, chair, and foot-rest thereon; Fig. 2,a side elevation of the chair, pedestal, foot-rest, and mechanism forcarrying the back of the chair to an inclined position and the seat andfootrest to a forward position. Fig. 3 is a detail of a section of thepedestal and top plates provided with grooves and ball-bearings, anL-shape strip countersunk in the pedestal, and a locking device. Fig. 4is a detail top view of the lock-rod held in a recess between twoshoulders. Fig. 5 is a detail of a channel-bar'and one of its rollers.Fig. 6 is a detail of mechanism under the chair-seat, showing the leverconnection with a cross-bar and its lug, shown by dotted lines, thatengages with teeth on a plate fastened rigidly to the seat-bottom andFig. 7 is a detail top view of the pedestal-plate groove, showing one ofits partitions and ball-bearings.

Similar letters refer to similar parts in the several views.

A A represent the chair pedestal and frame,B the chair-seat, and C thechair-back, hinged at its bottom to the back of the seat.

The arms D D are pivoted at their front ends to frame-posts A A and atthe rear ends to.

the back of the chair. To permit the chair to revolve, we attach a plateE rigidly on the top of the chair-pedestal E, and 'a plate F,

spaced from the bottom of the chair-seat, is carried by frame-pieces ofthe chair. In these upper and lower plates are corresponding circulargrooves e e, in which ball-bearings H H are adapted to travel. Toprevent 5 5 said ball-bearings massing in one part of the groove, weprovide partitions h h with one or more bearings for each division. Twometal L-shape strips rigidly attached at their upper ends to oppositeside edges of plate F en gage with and travel in groove 1, whichencircles said pedestal. These L-shape pieces are adapted to securelyhold the chair in po sition. The front edge of plate F is provided withduplicate rounded shouldersJ J, which form a recess J. A vertical rod Kis pivotally carried at its lower end by brackets 7c k on the front ofthe pedestal. At the front of said rod there is a spring K, whichconstantly bears against it,holding the upper end in re, cess J andpreventing the chair being revolved unless released by the porter orother person by drawing said rod out of the recess by the use of ahooked pin or other device inserted into perforation in the top of saidrod. Frame-pieces A A at the sides of the seat are provided with rollersM M, and the side edges of the seat are provided with channel-bars M M,adapted to engage with and travel on said rollers. If preferred, thisarrangement may be reversed without altering the scope of our invention,said rollers being attached to the side edges of the seat and thechannel-bars countersunk in the frame-pieces. Two cleats O O are rigidlyattached at their upper ends on the lower part of the back of the chair.A foldable footrest P is carried by two supporters P P, pivotallyattached to the front edge of the seat. Connecting-rods O O are attachedpivotally to the bottom ends of said cleats and to said supporters atpoints about half-way between the chair-seat and the foot-rest. Rigidlyfastened on the bottom of said seat centrally between front and back isan elongated plate Q, 9 5 provided on one edge with a plurality ofoneway teeth q q. Below said plate, at right angles therewith, is ametal strip Q, with a sin gle projecting lu q adapted to engage with theteeth on said plate. This strip engages Io'o loosely with a slot (1(shown by dotted lines in Fig. 6) in one of the side pieces of the frameof the chair. Upon the opposite side alever R operates verticallythrough a frame-piece carrying a rigidly-fastened arm S, which pro- 10 5jects at a right angle with strip Q and on the projecting end of whichsaid strip is pivoted. Below the slot in which said strip operates inthe frame piece a coil-spring T is rigidly attached at one end, theother end being rigidly fastened to the bottom of said strip, preferablyin proximity to plate Q. By a half-turn of lever R said strip is drawnpartially out of its slot, this movement releasing said lug g from itsnormal position of engagement with teeth (1 g on plate Q. While thelever is thus held at its half-turn, the seat of the chair remainsreleased, and the chair can be readily adjusted to the desired incline.Thelever being released, spring T will instantly draw the end of strip Qinto its normal position in its slot, thus carrying lug g intoengagement with other teeth and holding the chair in its changedposition. What we claim, and desire to secure by Letters Patent, is p Ina r'evol'uble reclining coach-chair the combination with the pedestal,frame and back, of arm-posts at the front of the frame,

' arms 'pivotally attached to said posts and the sides of the chairback, cleats extending downwardfrom the chair-back and rigidly attachedthereto, a foldable foot-rest and the duplicate supporters thereforpivotally carried on the front edge of the seat-frame, duplicate rodshavin pivotal connection with said supporters an cleats, a plate rigidlyfastened on top of the pedestal provided with a partitioned groove, aplate carried by the chair-frame spaced below the chair-seat andprovided with a groove, the roller-bearings adapted to travel in saidpartitioned groove, L-shape metal strips ri idly fastened to the edge ofthe top plate an adapted to travel in a groove in the pedestal as thechair revolves, shoulders forming a recess and brackets pivotallysupporting a lock-rod provided with a perforation in its upper end andadapted to engage with said recess and a spring to hold said rod back insaid recess, channel-bars and their rollers between which the chair-seattravels backward and forward, a lever and its arm carried in a sideframe-piece, a strip pivotally attached to said arm at one end, the

opposite end carried in a slot in an opposite frame piece, a lug thereonprojecting upward and a plate at aright angle with said strip rigidlyattached to the bottom of the chair-seat and provided with one-way teethwithwhic'h said lug is adapted to engage, substantially as shown anddescribed.

In testimony whereof we aflix our signatures in presence of twowitnesses.
